  • the polyvinyl butyral sheet becomes oxidized and undergoes color development and change. Accordingly, the film layers at the peripheral portions are removed, and the glass plates and the polyvinyl butyral sheet, which are easily bonded to each other, are bonded to each other.

  • the movable base 7 is moved away from the glass-plate placing surface 3 by the moving means 8 upon detection by the detecting means 17 for detecting the lifted or lowered position of the grinding wheel 9 with respect to the movable base 7 , e.g., upon detection of the lowering of the grinding wheel 9 below a predetermined position with respect to the movable base 7 on the basis of the passing of the grinding wheel 9 past the edge portion 100 of the glass plate 2 .
  • the operation of causing the movable base 7 to approach the glass-plate placing surface 3 by the moving means 8 is stopped upon detection by the detecting means 17 of the lifting of the grinding wheel 9 above a predetermined position with respect to the movable base 7 , which is caused by the abutment of the grinding wheel 9 against the glass plate 2 .
  • the grinding wheel 9 can be thereby made to abut against the glass plate 2 with a predetermined pressing force even if the diameter of the grinding wheel 9 has become small.
  • the film layer 14 can be removed, as desired, even with the grinding wheel 9 whose diameter has become small due to wear, thereby making it possible to avoid a decline in the manufacturing efficiency which is ascribable to the operation of replacing the grinding wheel 9 .
  • a cutter wheel instead of the grinding wheel 9 , is rotatably attached at an extended lower end portion of the spline shaft 61 or at a lower end portion of the L-shaped connecting member 64 , i.e., at a position equivalent to the position where the output rotating shaft 82 of the air motor 81 is disposed.
  • the air motor 81 may not be provided.
  • the present invention is not limited to the same.
